Examination of the interobserver variability among the ten observers of the 2-deg Stiles and Burch colorimetric study reveals an interesting pattern: the chromaticities of the matches made by different normal subjects fall approximately on straight lines and these lines appear to converge. Because of a geometric relationship that holds between the normal, anomalous, and dichromatic colour spaces, it can be argued that part of the variability must be due to actual differences in the shape or spectral position of the receptor sensitivities of different normal observers.
对2度斯泰尔斯和伯奇比色研究中十位观察者之间的观察者间变异性进行检查后发现了一个有趣的模式：不同正常受试者做出的匹配色度大致落在直线上，并且这些直线似乎会相交。由于正常、异常和双色空间之间存在一种几何关系，可以认为部分变异性必定是由于不同正常观察者的受体敏感度在形状或光谱位置上的实际差异所致。
